These figures cover 357 flights between July 2025 and June 2026. Beyond the headline rate, 12.6% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.

Schedule

When B6 1475 flies

B6 1475 flies BDL to SJU without a single fixed slot. Its most common scheduled departure was 08:15, used on 53 of 357 flights. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Scale runs 0% to 100%. Rows with fewer than 30 flights show a dash.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.

A 08:15 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and B6 1475 runs 15 points worse at 68.9%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Across the year

B6 1475 quarter by quarter

B6 1475 did not run the same all year. Its best quarter was Jul–Sep 2025 at 83.3% on time and its weakest Jan–Mar 2026 at 55.4%, a swing of 28 points on roughly 89 flights a quarter. The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.

Oct–Dec 202588 flights66.3%
Jan–Mar 202686 flights55.4%

By weekday, B6 1475 did best on Thursday at 76.0% on time and worst on Monday at 58.8%. Each day rests on about 51 flights, so a gap of 17 points is worth noticing but could still narrow in another year.

Delay causes

Why B6 1475 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 45% of the 9,076 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.

Carrier
35%

45% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 9,076 reported delay minutes here, that single category outweighs weather by 45 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 9,076 delay minutes reported on B6 1475.

Cancellations sit at 1.12% against a national 1.81%, which is ordinary. Diversions add another 0.84%.

Connections and routes

What a delay on this flight costs

For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 12.6% of arrivals land a full hour or more behind schedule, against 8.1% nationally. A 45-minute layover does not survive that, and no amount of walking quickly changes it. Ninety minutes is the honest minimum here, and two hours if the onward flight is on a separate ticket.

At 1,666 miles this is transcontinental flying, and long routes get a quiet structural advantage. Scheduled block time on a flight this length carries more padding in absolute minutes, so a twenty-minute late departure often still becomes an on-time arrival. Read the on-time rate here as slightly flattering next to a short-haul route with the same operational quality.

Every one of the 357 flights under B6 1475 in the data flew BDL to SJU. The number was not reused on any other city pair, which makes this a clean record of one route.

One caution: this is a thin sample. 357 flights over twelve months is enough to clear this site's floor but not enough to pin the rate down tightly, and a single bad week moves it by more than a point. Treat the grade as a rough reading.

What to do with this

Booking B6 1475

For a booking, B6 1475 is a flight to put a long connection behind. 12.6% of its completed flights arrived an hour or more late, which a short layover will not absorb. If the onward flight is on a separate ticket, the risk sits with you.
